We recently posted our first review of a notebook equipped with NVIDIA’s latest mobile tour de force, the GeForce GTX 780M. With a theoretical computational performance increase of 30% relative to GTX 680M and 39% more memory bandwidth, the GTX 780M should be stomping all over the competition from AMD. What’s more, the Radeon HD 8970M doesn’t really help matters, as the only change from the 7970M is a Boost clock that’s 50MHz (6%) higher. The other side of the story is drivers, and that's the focus for today.
